A shaded computer graphics system for sensor simulation and animation must possess extensive capabilities. Sensor simulation involves scenes that are viewed, environments that produce tones in the scenes, and sensors that image the scenes. Animation centers on image generation, but data input, motion specification, and tone specification routines are very important for an effective system.A unique system has been developed that models a variety of scenes, environments, and sensors. It possesses a balance of data input, motion and tone specification, and frame generation routines. The system possesses several user languages for data input. User defined sections of the scene can move. Visible, infrared, laser radar, and radar sensors have been modeled. The frame generator possesses advanced aliasing controls, textured shading, and a very fast list priority hidden surface algorithm. The system is used as a test bed for training simulators and sensor-based system simulation.
